Selection of Host Plasma Membrane Lipids by HIV‐1 Gag Protein

BioEssays, Volume 48, Issue 1, January 2026.
Enrichment of sphingomyelin in the HIV‐1 envelope arises from Gag binding to PI(4,5)P2, which triggers reorganization of plasma membrane sphingomyelin/cholesterol domains through unknown mechanisms. We propose that cholesterol‐mediated interleaflet coupling between sphingomyelin and PI(4,5)P2, rather than interdigitation, underlies Gag‐induced lipid ...

A Comprehensive Study on Light Signals of Opportunity for Subdecimetre Unmodulated Visible Light Positioning

Sensors, 2020
Currently, visible light positioning (VLP) enabling an illumination infrastructure requires a costly retrofit. Intensity modulation systems not only necessitate changes to the internal LED driving module, but decrease the LEDs’ radiant flux as well. This

Unnatural Amino Acid Incorporation into Virus-Like Particles [PDF]

, 2008
Virus-like particles composed of hepatitis B virus (HBV) or bacteriophage Qβ capsid proteins have been labeled with azide- or alkyne-containing unnatural amino acids by expression in a methionine auxotrophic strain of E. coli.

Arbitrary polarization control with a segmented APPLE‐II undulator

Journal of Synchrotron Radiation, Volume 33, Issue 1, Page 73-83, January 2026.
A four‐segmented APPLE‐II undulator was constructed, and its operation has started at NanoTerasu BL13U. The performance of arbitrary polarization control using phase shifters is demonstrated.A newly developed four‐segmented APPLE‐II undulator enables arbitrary polarization control in the soft to tender X‐ray region.

Efficacy and Safety of Conservative and Surgical Treatment in the Treatment of Distal Radius Fractures: A Systematic Review and Meta‐Analysis

Orthopaedic Surgery, Volume 18, Issue 1, Page 31-52, January 2026.
A systematic review and meta‐analysis covering 19 studies comparing surgical versus conservative fixation for distal radius fractures. ABSTRACT To assess whether surgical treatment with predominantly volar locking plates has superior clinical and radiographic outcomes to conservative treatment with cast immobilization in the treatment of distal radius ...
